In water pipe work in which a pipe 1' that detours around point A is installed in place of the removed pipe section 1A to maintain water supply through the existing water pipe 1, a detour water pipe 1' is installed in the existing water pipe 1.
Both ends of the existing water pipe 1 are connected in communication with both ends of the detour water pipe 1', and connection points B,
In each case B', the pipe section located between the two connection points B and B', that is, the pipe section 1A to be removed.
This is a structure that is adopted when cutting off water flow to a fluid transport pipe, and more specifically, two ends of a fluid transport pipe created by cutting and removing a pipe portion over an appropriate length;
A case is provided that interconnects the ends of another fluid transport pipe, and blocks fluid flow between the ends of the fluid transport pipe, and one of the ends of the fluid transport pipe. The present invention relates to a connection structure for a fluid transport pipe, in which a partition is provided to partition the inside of the case so that only one end of the fluid transport pipe communicates with an end of another fluid transport pipe.

In the conventional connection structure of this type of fluid transport pipe, the partition plate 3 has a flat plate as shown in FIG. 8A, or as shown in FIG. 8B, A curved portion 3a for guiding fluid flow was formed in the partition body 3. 1a, 1 in the figure
b and 1a' are a fluid transport pipe end and another fluid transport pipe end, and 2 is a case.

However, in both of the above two conventional structures, the end of the fluid transport pipe has a chamber of the case partitioned by a partition, that is, a chamber itself that has a cross-sectional shape different from that of the fluid transport pipe. This allows fluid to flow between the end of the fluid transport pipe and the end of another fluid transport pipe. The drawback is that sometimes excessive eddies and turbulence are unavoidable, resulting in very large pressure losses and flow resistance.
本考案は、かかる従来欠点を解消しようとする

The technical means of the present invention taken to achieve the above object is to separate the two ends of a fluid transport pipe, which are created by cutting and removing a pipe portion over an appropriate length, and the end of another fluid transport pipe. A case is provided that allows the three to communicate with each other, and also blocks fluid flow between the ends of the fluid transport pipe and connects only one of the ends of the fluid transport pipe to another fluid transport pipe end. The connection structure for a fluid transport pipe is provided with a partition body that partitions the inside of the case so as to communicate with the inside of the case, and includes the configurations described in [A] and [B] below.

ることを極力抑制できる。a In other words, the fluid flow is guided between the end of the fluid transport pipe and the end of another fluid transport pipe by a pipe section having a flow path cross-sectional area comparable to that of each fluid transport pipe, which eliminates the conventional bias. Compared to the case where the fluid is guided by a flat or curved plate-like partition, the fluid flowing out from the end of the fluid transport pipe is guided through a case that has a bend or a space where the cross-sectional area of the flow path changes abruptly. It is possible to suppress as much as possible the occurrence of a situation where the flow is disturbed and a vortex or turbulent flow occurs.

業も簡単に行える。(b) Moreover, since the guiding pipe portion is fixed to the partition, it can be used as a means for reinforcing the partition, and it is possible to simply attach the partition to the case without requiring any special effort. The pipe part can be attached at the same time, making the installation process easy.
